Grenoble, France

A training plateform

• Increase engagement and autonomy of students
• Better use of teacher time
• Improve the quality of the contents

– (sharing = reviewing from others)

• Improve visibility of the contents

– (communication)

• Automatic evaluation

– Linear programming – Mixed Integer Programming – Dynamic programming – Graph algorithms – Others : Java, Python, C, R…

• An environment for the students
• A community sharing resources

– The principle – How to join?

To edit the program The program of the student To run the evaluation Result of the evaluation A comment from the teacher

A programming activity: Student’s point of view

Automatic evaluation

The teacher: describes the exercice The student: enters the code/model lauches the evaluation gets the results The teacher: can access the code can comment the code

Automatic evaluation

• Based on VPL tool

– A Moodle plugin – vpl.dis.ulpgc.es

• Used on Caseine for

– LP, MIP models – CP models – Dynamic programming – Graph algorithms and data structures – Basic and advanced programming

• Java, Python, C…

– R

LP/Cucumber and Onions

Evaluate an LP model

• Check the vertices of the polyhedron defined

by the constraints

• Give information to the student
• Semi-automatic generation of tests

LP/Cucumber and Onions

Evaluate an LP model

Evaluate a MIP model

MIP/Maximum matching

External Data Forall, sum… Execution control

Evaluate dynamic programs

• In Java
• Tests in Junit
• Complexity check

– Time control: Distinguish pseudo-polynomial from complete enumeration – More precise ?

• Backtrack check

DP/Load balancing

Evaluate dynamic programs

DP/Load balancing

Evaluate dynamic programs

DP/Load balancing

Evaluate graph algorithms

• In Java

– (and some in Python)

• Tests in Junit
• Classical algorithms

– Simple problems: max degree, number of connected components… – Graph representation – BFS, DFS – Dijkstra, Kruskal, Ford-Fulkerson…

DP/Load balancing

OR automatic evaluation

• Ideas to test smartly the students program
• Time consuming development -> share
• What’s next

– Other ideas – More fluent use for teachers – Enhance the collection of exercices – Share with broader community

A pedagological environment

• Based on Moodle
• Plugin development

– VPL questions – Completion levels – Likes – Ski run color

A pedagological environment

• Open to academic community:

edugain connexion

– Belnet federation, DFN-AAI…

The teacher community of Caseine

• A shared space i.e. a feature to easily:

– Tag/mark your activities with relevant information for sharing – Share your activities – Search among the shared activities

• How to join

– Create an account (your existing academic login might work) – Have a look at the opened courses (e.g. OR course) – Have a look at the tutorial (key to enter the tutorial: cincle) – Express your will (send an email) for starting a course and have access to the shared space.

• Support and training for a start…

The teacher community of Caseine

• Access to open courses: Free for initial university courses

and individual training

• Creating a course

– Free for initial university courses – Contribution to costs for lifelong university training (formation continue) – Paying service for companies which sell formations

• Terms

– Everyone is author of its creations – Everyone can choose to share or not – Moodle developments (shared plugins) – Caseine specific developments

Community animation tools

• Tutorial

– Discussion Forum – FAQ – Instructions for Caseine specific features – Newsletter link in Tutorial

• Association model to financially ensure the

continued existence of the platform

(handled by Grenoble university for the moment) – Fees for the hosting, Administration, Development, Maintenance, Support

Variety of usages

Support for « active classrooms » but as many practices as there are teachers:

Autonomy Personal work Autonomy Team work Autonomy Personal work at home Only one agreement: focus on student’s active role Individual Evaluation Support to conduct a flipped classroom Traditional classroom with validation in autonomy

Core team

Quantities in 17-18

• Academic use

– 1200 active students – 14 bachelor / 11 master training programs – 5 universities (in courses)

• UGA, Grenoble INP, INSA de Lyon, Université Clermont

Auvergne, Centrale Lille

– 36 teachers

• + free connexions from everywhere

A training plateform

• Increase engagement and autonomy of students
• Better use of teacher time
• Improve the quality of the contents (sharing = reviewing from
• thers)
• Improve visibility of the contents (communication)
